Question 345162
A)

For each number from 15 (the smallest number here) to 52 (the largest number here), count how many times that number shows up in the given list to make the frequency table shown below. Eg. 36 shows up 6 times. So you'll write "6" as the frequency of 36.



Frequency Table:

<table border=1><th>Value</th><th>Frequency</th><tr><td>15</td><td>1</td></tr><tr><td>16</td><td>0</td></tr><tr><td>17</td><td>0</td></tr><tr><td>18</td><td>0</td></tr><tr><td>19</td><td>0</td></tr><tr><td>20</td><td>1</td></tr><tr><td>21</td><td>0</td></tr><tr><td>22</td><td>0</td></tr><tr><td>23</td><td>1</td></tr><tr><td>24</td><td>1</td></tr><tr><td>25</td><td>0</td></tr><tr><td>26</td><td>0</td></tr><tr><td>27</td><td>1</td></tr><tr><td>28</td><td>1</td></tr><tr><td>29</td><td>0</td></tr><tr><td>30</td><td>3</td></tr><tr><td>31</td><td>3</td></tr><tr><td>32</td><td>3</td></tr><tr><td>33</td><td>2</td></tr><tr><td>34</td><td>4</td></tr><tr><td>35</td><td>2</td></tr><tr><td>36</td><td>6</td></tr><tr><td>37</td><td>2</td></tr><tr><td>38</td><td>1</td></tr><tr><td>39</td><td>0</td></tr><tr><td>40</td><td>3</td></tr><tr><td>41</td><td>0</td></tr><tr><td>42</td><td>1</td></tr><tr><td>43</td><td>0</td></tr><tr><td>44</td><td>0</td></tr><tr><td>45</td><td>1</td></tr><tr><td>46</td><td>1</td></tr><tr><td>47</td><td>0</td></tr><tr><td>48</td><td>0</td></tr><tr><td>49</td><td>0</td></tr><tr><td>50</td><td>0</td></tr><tr><td>51</td><td>0</td></tr><tr><td>52</td><td>2</td></tr></table>

B)


Construct the histogram to get

Here I have 8 groups where each group is 4 units wide (eg: group 1 is 15-19). I've also included the frequency of each group at the top of each bar.

C)


The general shape is approximately bell shaped. Notice how we can draw a bell shaped curve over the histogram like so

and notice how the shape of the histogram fits that curve
